Apple adopts new ‘BlastDoor’ security system on iOS 14 to reinforce iMessage integrity

From 9To5Mac:

iOS 14 was announced with some great new features for iMessage, including more options for group conversations, inline replies, and more. However, there’s also an important change in iMessage that Apple hasn’t mentioned so far. The company has adopted a new security system called “BlastDoor,” which is basically a sandbox mode that protects the Messages app from the rest of iOS.

As reported by ZDNet, this new security feature of iOS 14 was discovered by Samuel Groß, a security researcher working with Google’s Project Zero. All iOS apps already work in sandbox mode by default, but BlastDoor adds an extra layer of protection to iMessage.

“Its role is to take incoming messages and unpack and process their content inside a secure and isolated environment, where any malicious code hidden inside a message can’t interact or harm the underlying operating system or retrieve with user data.”

Great news.
